JAR 0R BOTTLE CLOSURE.

SPECIFICATION forming part of Letters Fatent No. 742,652, dated October27, 1903.

Application filed May 18, 1903. erial No. 157.640.

To all whom it may concern.-

Be it known that I, JAMES HIRST, a citizen of the United States,residing at Vineland, Cumberland county, New Jersey, have inventedcertain Improvements in Jar or Bottle Closures, of which the followingis a specification.

My invention relates to jar or bottle stoppers; and it consists of animproved form of paper disk stopper or sealing-cap of the characterusually employed in connection with milk-bottles for the purpose ofmaking a temporary air and liquid tight closure.

My invention is fully shown in the accompanying drawings, in which-Figure 1 is a sectional view of the improved sealing-cap forming thesubject of my invention shown as applied to a bottle. Fig. 2 is aperspective view of the cap 1; and

proximately to the size of a shouldered recess in the inner wall of thebottle-neck. These caps or disks are pressed into place by spitablemeans and engage the inner wall of the In this position the caps makequite a tight fit, and it is usually a difficult matter to remove thesame. Numerous means have been suggested and provided for accomplishingthis result. Such means usually comprised the combination with thestopper of an extra element designed to serve as a projection or handleto be grasped by the thumb and finger, whereby the cap might be removedin a comparatively easy manner. Such seals or stopper, however, havingthe additional element noted are more expensive than their valuewarrants. Hence the use of the ordinary plain flat disk has not beensuperseded to any great extent. My invention provides means for removingthe cap integral with such cap, which means do not add to the expense ofthe same and consist in forming a projection within and from thematerial of which the cap is composed, which projection may be graspedby the thumb and finger to accomplish the removal of the cap.

In the preferred form of structure embody- 7 shown in Fig. Figs. 3, 4,5, and .6 are views illustrate ing modified structures embodying myinven (No modeld ing my invention, as illustrated in Figs. 1 and 2, 1represents the main or fiat portion of the disk, fitting the shoulderedrecess 2 of the bottle 3. Extending above the main flat portion of thecap is a projection 4, preferably disposed in the center of the cap andwhich may or may not have a contracted neck portion. By grasping thisprojection with the thumb and finger the disk or cap 1 is contractedtoward the center, causing the edges opposite the thumb and finger toleave the shouldered recess, and the cap is thereby rendered readilyremovable. At the same time the initial compression of the walls of theprojection4 will effect more or less compres-- sion of the air betweenthe surface of theliquid in the bottle and the under surface of the cap,and such compression of the air will tend to lift the cap at the centerand assist in the removal of the same.

In the modification shown in Figs. 3 and 6 the projection 4 compriseswalls of the material which have been brought together or compressed, asshown, and this form provides simply an engaging means for the thumb andfinger and affords no compressing efiect upon the air within the bottle.

In Fig. 4=Ihave shown a form of cap or disk in which a bulbousprojection 4 is provided with a contracted neck portion 5.

In Fig. 5 I have shown a form of disk in which the projection 4 bunchingup the central portion of the material of which the cap or disk iscomposed.

Having thus described my invention, I

claim and desire to secure by Letters Patcut- 1. As a new article ofmanufacture, a jar or bottle closure comprising a sealing-disk having anintegral projection struck up from the material'of which the disk iscomposed, said projection being discontinued some distance from theedges of said disk.

2. Asa new article of manufacture, a jar or bottle closure comprising asealing-disk having an integral projection struck up from the materialof which the disk is composed, and confined to the central portion ofthe disk. I 3. As a new article of manufacture, a jar or bottle closurecomprising a sealing-disk having a bulbous projection struck up from thematerial of which the disk is composed.

is made by simply 4. As a new article of manufacture, a jar or bottleclosure comprising a sealing-disk having a fiat portion of circularshape adapted to fit within a recess in the neck of a bottle and havingan integral, struck up, bulbous member projecting from the upper surfaceof the same. v

5. As a new article of manufacture, a jar or bottle closure composedofan integral member of pasteboard or paper of circular shape adapted tofit within the recess of a bottleneck and having an integral hollowbulbous projection struck up from the surface of the disk, saidprojection serving as a handle for the finger and thumb in removing saiddisk. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
